Hebrides
The Hebrides (; gd, Innse Gall, ; non, Suðreyjar, "southern isles") are an archipelago off the west coast of the Scottish mainland. The islands fall into two main groups, based on their proximity to the mainland: the Inner and Outer Hebrides. These islands have a long history of occupation (dating back to the Mesolithic period), and the culture of the inhabitants has been successively influenced by the cultures of Celtic-speaking, Norse-speaking, and English-speaking peoples. This diversity is reflected in the various names given to the islands, which are derived from the different languages that have been spoken there at various points in their history. The Hebrides are where much of Scottish Gaelic literature and Gaelic music has historically originated. Today, the economy of the islands is dependent on crofting, fishing, tourism, the oil industry, and renewable energy. The Hebrides have less biodiversity than mainland Scotland, but a significant number of seals an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jamaica
Jamaica (; ) is an island country situated in the Caribbean Sea. Spanning in area, it is the third-largest island of the Greater Antilles and the Caribbean (after Cuba and Hispaniola). Jamaica lies about south of Cuba, and west of Hispaniola (the island containing the countries of Haiti and the Dominican Republic); the British Overseas Territory of the Cayman Islands lies some to the north-west. Originally inhabited by the indigenous Taíno peoples, the island came under Spanish rule following the arrival of Christopher Columbus in 1494. Many of the indigenous people either were killed or died of diseases, after which the Spanish brought large numbers of African slaves to Jamaica as labourers. The island remained a possession of Spain until 1655, when England (later Great Britain) conquered it, renaming it ''Jamaica''. Under British colonial rule Jamaica became a leading sugar exporter, with a plantation economy dependent on the African slaves and later their des ...

Researches in mycology Around 1910 Pearson began to research the larger fungi, encouraged by John Ramsbottom, mycologist at the Natural History Museum. His initial papers, co-authored by E. M. Wakefield, were on British corticioid fungi and heterobasidiomycetes, but he subsequently developed an expertise in the taxonomy of agarics, publishing a series of papers on this group of fungi from ...
